Important Safety Instructions

IMPORTANT: READ AND SAVE THIS OWNER’S GUIDE FOR FUTURE

REFERENCE.

This chapter contains important safety and installation instructions for the
Freedom SW Inverter/Charger (Freedom SW). Each time, before using the
Freedom SW, READ ALL instructions and cautionary markings on or
provided with the inverter/charger, the batteries, and all appropriate sections
of this guide.

NOTE: The Freedom SW contains no user-serviceable parts.

ELECTRICAL SHOCK HAZARD

• Do not expose the Freedom SW to rain, snow, spray, or bilge water.
This inverter/charger is designed for marine applications only when
additional drip protection is installed in certain orientations. See the
installation guide for information.

• Do not operate the inverter/charger if it has received a sharp blow,
been dropped, has cracks or openings in the enclosure including if the
fuse cover has been lost, damaged, or will not close, or otherwise
damaged in any other way.

• Do not disassemble the inverter/charger. Internal capacitors remain
charged after all power is disconnected.

• Disconnect both AC and DC power from the inverter/charger before
attempting any maintenance or cleaning or working on any circuits
connected to the inverter/charger. See note below.

• Do not operate the inverter/charger with damaged or substandard
wiring. Make sure that all wiring is in good condition and is not
undersized.

NOTE: Turning off the inverter/charger using the on/off switch on the front
panel will not reduce an electrical shock hazard.

FIRE AND BURN HAZARD

• Do not cover or obstruct the air intake vent openings and/or install in
a zero-clearance compartment.

• Do not use transformerless battery chargers in conjunction with the
inverter/charger due to overheating.

EXPLOSION HAZARD

• Charge only properly rated (such as 12 V) lead-acid (GEL, AGM,
Flooded, or lead-calcium) rechargeable batteries because other
battery types may explode.

• Do not work in the vicinity of lead-acid batteries. Batteries generate
explosive gases during normal operation. See note #1.

• Do not install and/or operate in compartments containing flammable
materials or in locations that require ignition-protected equipment.
See notes #2 and #3.

NOTES:

1. Follow these instructions and those published by the battery
manufacturer and the manufacturer of any equipment you intend to use
in the vicinity of the battery. Review cautionary markings on these
products and on the engine.

2. This inverter/charger contains components which tend to produce arcs
or sparks.

3. Locations include any space containing gasoline-powered machinery,
fuel tanks, as well as joints, fittings, or other connections between
components of the fuel system.

Precautions When Working With Batteries

BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE AND EXPLO­SION FROM VENTED GASES HAZARDS

• Always wear proper, non-absorbent gloves, complete eye protection,
and clothing protection. Avoid touching your eyes and wiping your
forehead while working near batteries. See note #4.

• Remove all personal metal items, like rings, bracelets, and watches
when working with batteries. See notes #5 and #6 below.

• Never smoke or allow a spark or flame near the engine or batteries.

• Never charge a frozen battery.

NOTES:

1. Mount and place the Freedom SW Inverter/Charger unit away from
batteries in a well ventilated compartment.

2. Always have someone within range of your voice or close enough to
come to your aid when you work near a lead-acid battery.

3. Always have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.

4. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with running
cold water for at least twenty minutes and get medical attention
immediately.

5. Use extra caution to reduce the risk or dropping a metal tool on the
battery. It could spark or short circuit the battery or other electrical
parts and could cause an explosion.

6. Batteries can produce a short circuit current high enough to weld a ring
or metal bracelet or the like to the battery terminal, causing a severe
burn.

7. When removing a battery, always remove the negative terminal from
the battery first for systems with grounded negative. If it is grounded
positive, remove the positive terminal first. Make sure all loads
connected to the battery and all accessories are off so you don’t cause
an arc.

Precautions When Preparing to Charge

EXPOSURE TO CHEMICALS AND GASES HAZARD

• Make sure the area around the battery is well ventilated.

• Make sure the voltage of the batteries matches the output voltage of
the inverter/charger.

• Be careful to keep corrosion from coming into contact with your eyes
and skin when cleaning battery terminals.

NOTES:

• Study and follow all of the battery manufacturer's specific precautions,
such as removing or not removing cell caps while charging, whether
equalization is acceptable for your battery, and recommended rates of
charge.

• For flooded non-sealed batteries, add distilled water in each cell until
battery acid reaches the level specified by the battery manufacturer.
This helps to purge excessive gas from cells. Do not overfill. For a
battery without removable cell caps, carefully follow manufacturer's
instructions.

Introduction

Key Features

The Freedom SW Inverter/Charger is a true sine wave inverter/charger that
can be used for mobile, marine and commercial applications. The Freedom
SW Inverter/Chargers are designed to operate with a wide variety of
generators and are capable of operating in parallel with a generator for short
durations to assist with starting large loads. The Freedom SW is a
convenient combination of an inverter, multistage battery charger, and
transfer switch in one electronic device.

• As an inverter, the Freedom SW provides true sine wave power for
your microwave, entertainment system, computer, and other loads.
This power is identical to the AC source provided from the utility grid
(power company).

• Some of the benefits of true sine wave power include consistent
cooking in your microwave, handling of sensitive loads such as your
TV set, dimmer switches, and appliances with speed controls.

• Highly versatile platform capable of series stacking for 120/240V line
configurations and parallel stacking to increase power levels.

• High efficiency true sine wave output to power sensitive electrical and
electronic equipment.

• Surge capacity to start difficult loads like well pumps, refrigerators, or
A/C compressors.

• Power factor-corrected (PFC) input minimizes AC input current
required for charging, increasing AC pass-through capacity.

• As a charger, it has high output, multi-stage charging capability
minimizing charging time.

• Capable of operating from 50Hz and 60Hz power source by extending
AC qualification frequency range. See “ACIn Settings” on page 52.

IMPORTANT: Dual Line models require only the Line 1 Input to be
energized in order to qualify AC. Line 2 Input does not have to be
powered in a single phase system.

• Temperature-controlled, variable-speed internal cooling fans. The fans
turn on when the internal temperature reaches 45 °C (113 °F) and
reaches maximum speed at 70 °C (158 °F). The fan turns off when the
internal temperature falls to 40 °C (104 °F).

• Designed with efficient field serviceability in mind.

• The Freedom SW Inverter/Charger is also Xanbus-enabled which
allows network compatibility and communication with other Xanbus­enabled devices. See more information under “System Components”
on page 6.

Key Features Explained

Built-in Charge Formulas For the unit to perform at the highest level,
the batteries must be charged correctly. The Freedom SW has optimized
algorithms for flooded, gel, and AGM batteries.

Battery Temperature Sensor Since battery temperature is a key factor in
correct charging, the charging formula must be adjusted (automatically and
in real time) according to the actual battery temperature to ensure that
batteries are fully charged, but not overcharged. For this reason, a battery
temperature sensor is included with your Freedom SW and has temperature
compensated the charge formula.

2 Freedom SW Owner’s Guide

Freedom SW 3K2K InvChg Owners Guide.book Page 3 Wednesday, October 9, 2013 1:34 PM

Manual Equalization Over a period of time, the cells in a flooded
battery can develop uneven chemical states. This can result in a weak
(undercharged) cell which, in turn, can reduce the overall capacity of the
battery. To improve the life and performance of a non-sealed, flooded
battery, the Freedom SW’s multi-stage charging cycle includes a manual
equalize mode that can be used, if recommended by the battery
manufacturer.

Dead Battery Charging Another feature that the Freedom SW includes
is dead battery charging. The Freedom SW—unlike many chargers—has
the ability to recharge batteries even if the battery voltage is very low, i.e.,
as low as 3 volts.

Load Management The Freedom SW has a built-in transfer relay that
connects your inverter output or AC input from the utility grid or generator
to your loads. Because the usual AC power sources such as campground
outlets or small generators often have limited current availability, having
the capability to manage your AC loads is extremely valuable. The
Freedom SW provides a number of features to facilitate this:

• The charger is power factor corrected to use AC current as efficiently
as possible. Minimizing the AC current used by the charger means
more current is available for your AC loads.

• Freedom SW has a power share feature which prioritizes your AC
loads by reducing the charge current and maintaining the total input
current to less than the breaker setting.

Occasionally, AC input sources have low voltage. To avoid loading these
weak sources any further, the charger automatically reduces its AC current
draw as the AC voltage approaches the minimum acceptable level.

Introduction

Stacking

Supports stacking of two inverter/chargers to increase capacity. This also
requires the installer to select a Master and Slave in order for the inverters
to stack. Two configurations of stacking are supported: Parallel stacking
and Series stacking.

Parallel Stacking

Parallel stacking allows two inverter/chargers to operate in parallel thereby
doubling the capacity in inverter mode. The two inverters communicate
over the network and intelligently share the load and to balance the load
between the two units. The Master Freedom SW broadcasts pulses on the
Xanbus network to synchronize operation between the other paralleled unit.
When AC loads are present, both units produce power, effectively sharing
the load. When Search mode is enabled, only the Master unit produces the
AC output.

Series Stacking

Two units can be configured to generate 120/240 Split-phase power for load
configurations that require both 120 and 240 volts. In this configuration, the
AC source must be split-phase as well.

97-0019-01-01 3

Freedom SW 3K2K InvChg Owners Guide.book Page 4 Wednesday, October 9, 2013 1:34 PM

Introduction

Stack Charging

Multiple Freedom SWs synchronize charging stages to ensure efficient
charging of the battery bank. When a single unit transitions from bulk to
absorption so do all other units. In absorption, all units must complete the
absorption stage before transitioning to the next stage. Note that units do
not load share when charging except during the bulk stage. The Freedom
SWs stop sharing charge current just before completing the bulk stage. The
units do not share charge current during the absorption and float stages.

Each unit charges batteries based on the Max Charge Rate setting and active
internal (temperature-based) deratings.

If equalization is enabled on one or more devices capable of equalization
charging, only those devices perform an equalize cycle after absorption.
Other devices transition to float (if three-stage charging is selected) or
transition to AC pass-through (if two-stage charging is selected).

Generator Assist

The Freedom SW Series of inverter/chargers can operate in tandem with a
generator to temporarily assist power loads with large start-up demands
such as air conditioners, water pumps etc. A Xanbus AGS must be installed
in the system in order for this feature work.

When this mode is enabled and generator capacity defined, the inverter will
come on-line and assist the generator when the generator reaches its
capacity. The battery bank must be well charged in order for the inverter to
engage this mode. For more details, see “Gen Support” on page 53.

Basic Protection Features

The Freedom SW has the following protection features:

• over temperature shutdown for critical components such as the
transformer and the power board

• battery temperature sensor (BTS) failure/battery temperature out-of­range fault protection

• DC output over voltage protection during charge mode,

• AC transfer relay failure detection

• AC output overload and short circuit protection during invert mode

• AC backfeed

• short circuit protection for the BTS and communication connector
ports including protection from incorrectly inserting the remote panel
communication cable plug into the BTS port and vice versa

protection

Introduction

The Battery Temperature Sensor (BTS) provides these protection features:

• battery over temperature charging protection preventing battery
charging at 60 °C (140 °F) or higher

• charging voltage compensation based on the temperature of the battery
the BTS is connected to

1.An AC backfeed error occurs when the AC output of the inverter/charger is con­nected or routed back to the inverter/charger’s AC input terminal or if the internal
transfer relay fails.

Freedom SW 3K2K InvChg Owners Guide.book Page 6 Wednesday, October 9, 2013 1:34 PM

System Components

The Freedom SW uses Xanbus, a network communications protocol
developed to communicate the Freedom SW’s settings and activity to other
Xanbus-enabled devices.

You can configure and monitor the Freedom SW and every Xanbus-enabled
device in the system using an optional Xanbus System Control Panel (SCP).

Another component is the optional Xanbus Automatic Generator Start
(AGS) which allows operation with a wide range of generators, supported
through a dedicated generator input. Simply, the AGS automatically starts
and stops your generator.

The Freedom Sequence Intelligent Power Manager is a fully integrated
power management system that provides automatic power and load
management for use in recreational vehicles (RV) while receiving power
from a generator or shore power. This device works in the background to
prevent monitored AC loads from exceeding shore and generator breaker
capacity.

See “Xanbus-enabled Products and Accessories” on page 7 for part
numbers.

Xanbus System

The Xanbus system includes the Freedom SW and other Xanbus-enabled
devices. The Freedom SW is the device in a Xanbus system that typically
provides network power—500 mA at 12 volts DC. All of the Xanbus­enabled devices, such as the Freedom SW, the SCP, and the AGS are able to
communicate their settings and activity to each other. See Figure 1.

Freedom Inverter/Charger Operation

Start Up Behavior

When the Freedom SW is powered up or has been reset, all of the front
panel lights illuminate and remain on for a minimum of five seconds.
During this interval, the fans are also turned on as the unit executes internal
diagnostics.

The Freedom SW inverter is disabled every time the Freedom SW is
powered up. After power up, the INVERTER ENABLE button (or the SCP)
can be used to enable or disable the inverter.

When a function is enabled, it is allowed to occur but other conditions may
have to be met before the function is activated or turned on. For example,
the charger function on the Freedom SW may be enabled, but it will not
charge unless qualified AC power is present.

Freedom Inverter/Charger Operation

Inverter Operation Using the Front Panel

IMPORTANT:

Review the “Important Safety Instructions” on page iv

before operating the inverter/charger.

Once the inverter/charger is installed, you can operate it in invert mode.

To operate in invert mode from the front panel:

1. Press the INVERTER ENABLE button on the Freedom SW on the front
panel. The INVERTER ENABLED LED illuminates and connected loads
will be energized.

2. Note that if AC is present and being passed through, the INVERTER
ENABLED LED will still illuminate to indicate inverter mode has been
enabled. However, AC will continue to be passed through to the loads
until conditions exist that cause AC to be disqualified, in which case
the unit will transition to invert mode and power up critical loads.

3. Connect AC input power.
The charger automatically starts up when qualified AC power is
connected.

To operate the inverter with the System Control Panel, refer to
“Operating the Freedom SW with the SCP” on page 15.

4. Disconnect AC power from inverter input by opening the breaker or
disconnect.

5. Place a load on the inverter. For example, plug a 100-watt light bulb
into an outlet that the inverter is powering. Press the INVERTER
ENABLE button on the Freedom SW. The INVERTER ENABLED LED
illuminates. The inverter should run the load using battery power.

6. To test the charger, reconnect the AC input power to allow AC to the
AC input. The AC/Charger On LED should start flashing after a brief
delay. Any AC loads previously powered by the inverter will also
work at this time.
NOTE: On dual input models, only AC Input L1 needs to be powered
for the unit to operate.

7. Remove the AC input power. The inverter/charger should transfer to
invert mode immediately. (The transfer relay will make a clicking
sound and the INVERTER ENABLED LED will illuminate.) Loads
should continue to operate uninterrupted.

If any part of this test fails, determine the cause before using the unit.

8. Monitor the Freedom SW Front Panel.

The indicator lights on the front panel show you the operating status of
the Freedom SW. A description of the lights is provided in Table 1.

If none of the front panel lights are on, see “Troubleshooting” on page

65.

Freedom Inverter/Charger Operation

Operating Limits for Inverter Operation

Temperature The Freedom SW series of inverter/chargers will operate at
rated power continuously at 30 °C with some models capable of continuous
operation at much higher ambient temperature. However, the continuous
power rating at elevated ambient temperature may differ between models.
See “Specifications” on page 77 for full details. In higher ambient
temperatures, if the loads draw full power for an extended period of time,
the unit may shut down to protect itself against overheating.

The Freedom SW series of inverter chargers feature a surge rating of 200%
of rated power for five seconds at 25 °C. Operating the inverter/charger in
conditions outside of power and temperature limits, however, will result in
thermal shutdown and/or significantly decreased performance. In addition,
operation in this range is outside the ratings covered by the regulatory
approvals of the product.

Difficulty on starting loads The inverter/charger should be able to
operate all AC loads rated at or below its power rating. Some high
horsepower induction motors used in pumps and other motor-operated
equipment require very high surge currents to start, and the inverter/charger
may have difficulty starting these loads.

If you have problems starting certain loads, ensure that:

• the battery connections are tight and clean.

• the DC cabling is no longer than the recommended length. Refer to the
Freedom SW Sine Wave Inverter/Chargers Installation Guide for this
information.

• the AC wiring is of recommended size. Refer to the Freedom SW Sine
Wave Inverter/Chargers Installation Guide for this information.

• the battery is of sufficient capacity and is fully charged.

Freedom Inverter/Charger Operation

Operating Limits for Charger Operation

By default, the maximum charger output current is the rated charger output
current for the particular model. Using the SCP, you can reduce the total
output if you change the maximum charge rate (Max Chg Rate) on the
Freedom SW Basic Settings menu or Inverter Settings menu under
Advanced Settings.

The charger can operate over an AC input range of 95–135 volts AC. This
is the default setting and can be adjusted to 78–145 volts AC as a maximum
range and to 110–120 volts AC as a minimum range. The charger can also
be configured to accept and operate from a wide AC source frequency of 40
to 70 Hz. The default setting is 55 to 65 Hz. This wide range allows the
Freedom SW to charge your batteries even when incoming AC voltage is
less than ideal or a 50 Hz source.

Power Share The Freedom SW charger uses AC input line 1 to charge
the batteries. The Freedom SW charger shares incoming power with AC
loads on line 1 only. The AC loads have priority, which means that the
charger will reduce its output with large AC loads and increase the output
again when the AC load decreases. The regulatory maximum for
continuous AC loads is 80% of the breaker rating that the loads are
connected to.

The Freedom SW senses pass-through current going to the AC load. The
difference between the pass-through (load) and 80% of the Power Share
setting is the current that is available for charging the batteries.

For example, if the AC input of the Freedom SW is from an AC panel with
a 30-amp breaker, the Power Share setting on the SCP should be selected as
30-amp. Based on this, the charger will control the charge current so that
the total current draw is equal to or less than 24 amps in this case. Should
the load current be more than about 24 amps, the charger output will reduce

to 0 amp, but the Freedom SW will continue to supply the loads. The
Freedom SW will continue to pass-through power to the loads, even if the
load current exceeds the Power Share setting. In this case, it will be up to
the user to remove/disconnect loads if tripping the AC input breaker
supplying the Freedom SW is to be avoided.

also refer to the Xanbus System Control Panel Owner’s Guide.

LIMITATIONS ON USE

• Do not use in connection with life support systems or other medical
equipment or devices.

• Do not use in ambulances or other life-saving emergency vehicles.

The SCP provides operating, configuration, and monitoring capability for
your Xanbus system.

The System Control Panel:

• Monitors activity throughout your onboard power system.

• Displays the latest information about your inverter/charger, battery
voltage level, battery charge output, and generator start and stop
activity.

• Displays the settings for each Xanbus-enabled device in the system.

• Enables you to adjust the settings for each Xanbus-enabled device in
the system.

• Preserves all of its settings if system power is interrupted. After power
is restored, you don’t have to reconfigure the SCP or any of the
Xanbus-enabled devices connected to it.

This section provides information on operating the Freedom SW with the
System Control Panel. Please refer to the System Control Panel Owner’s
Guide for complete information on using the System Control Panel.

Using Search Mode

Why use Search mode? Search mode allows the inverter to selectively
power only items that draw more than a certain amount of power, which can
result in power savings. The Freedom SW has a no-load power draw of
about 28 watts. Enabling search mode reduces this power draw to less than
8 watts. Search mode operates differently in single-unit and multi-unit
installations.

Single units When a single Freedom SW has search mode enabled, the
inverter sends electrical search pulses through its AC output. These search
pulses look for connected AC loads. The delay between search pulses is set
using the Search Delay setting. After a load larger than the Search
Watts setting is detected, the inverter starts producing AC output.

Multiple units When configured for 120/240-volt series stacking, each
inverter/charger operates independently in search mode and attempts to
detect loads connected to its terminals only.

To use search mode in parallel stacking, the Master unit must have Search
Mode disabled. The Slave unit must have Search Mode enabled.

IMPORTANT:

Master unit. If the Master unit has more than 60% of the rated load (e.g.,
1800 watts on Freedom SW 3012), the Slave unit will assist the Master and
the two will share the load equally. Should the load on the Master drop
below 20% of rated load (600 watts for Freedom SW 3012), the Slave unit
disengages and returns to a waiting state.

The Slave unit continuously monitors the output of the

34 Freedom SW Owner’s Guide

Freedom SW 3K2K InvChg Owners Guide.book Page 35 Wednesday, October 9, 2013 1:34 PM

When to set up Search mode The search mode feature is only valuable
if the inverter can spend a fair amount of time “sleeping” each day.
Therefore, if search mode is to be used it must be adjusted properly. The
initial adjustment should be made so that the inverter comes on only when
needed.

Certain types of loads can cause search mode to work unexpectedly. These
types of loads are described “Inverter Applications” on page 66. If these
kinds of loads are in the system, follow the suggestions given to eliminate
the problem.

If the problem loads cannot be eliminated, there are two work-around
solutions:

1. Disable search mode from the main Freedom SW Setup menu, causing
the inverter to always remain at full output voltage.

2. Use a search-friendly companion load whose only purpose is to be
switched on to wake up the inverter to power the load that is unable to
bring the inverter out of search mode.

NOTES:

• Search mode, by function, cannot work with clocks and timers or

devices that need power 24 hours a day. Examples of devices with
timers include video recorders, coffee makers with brew timers,
refrigerators, and freezers with defrost timers. Examples of devices
that need power 24 hours a day include telephone answering
machines, alarm systems, motion detection lights, and some
thermostats.

• When the inverter is searching the output for loads, lights that have a

wattage lower than this setting may flash momentarily.

Equalization Procedure

To start equalizing the batteries, do one of the following:

• Apply AC voltage and ensure that the inverter/charger transfers AC
and starts charging.

• On the Xanbus Setup menu, highlight Equalize and select Enable.
The unit will proceed and execute a complete bulk and absorption
charge before transitioning to equalize.
IMPORTANT: The inverter/charger will not perform equalization if AC
is not present, the charger is disabled, or the selected battery type does
not support equalization. If any of these cases happen, a warning is
issued

If the Freedom SW will not perform the equalization, see“Warning Types
and Behavior” on page 69.

EXPLOSION HAZARD

Only flooded or vented batteries should be equalize charged. Hydrogen
and oxygen gases are produced when batteries are equalize charged.
Provide adequate ventilation and remove all sources of ignition to prevent
explosion.

IMPORTANT:

equalizing batteries (such as multiple Freedom SWs), there is no system­wide equalization command for all devices. To equalize with multiple
devices, each would have to be enabled individually. Alternatively,
equalization can be performed using only one device. During the
equalization process, one device applies the equalization charge while the
other devices continue to operate in synchronized charge mode, typically in
float (three-stage charging) or no-float (two-stage charging).

Charger settings in a Dual Freedom SW con­figuration

The Freedom SW2012 includes a 100 A charger. When using two stacked
Freedom SW2012 inverter/chargers connected to the same battery bank, a
total of 200 A of bulk charging is possible into that single common battery
bank. For small battery banks and/or certain battery types this bulk mode
current may be too high, therefore Freedom SW models include the
“Battery Bank Capacity” and “Max Charge Rate” settings.

“Battery Bank Capacity” is the bank’s total Amp-hour capacity, this is
best determined by a qualified RV electrical technician, while the “Max
Charge Rate” is determined by the battery manufacturer/type of battery
model being used, i.e. Flooded, Gel, AGM being the most popular. For
“Flooded” type battery bank, the preferred charger capacity (A)/battery
bank capacity (Ah) is usually 10-15%C (C = Battery Bank Amp-hour
capacity), however the max charge rate allowable is often accepted as 25%
C, while some AGM or Gel battery models are higher (50% C or, in rare
cases, up to 100% C). Do not exceed battery manufacturers recommended
max charge specifications as resultant battery temperature rise will shorten
battery life.

(Charger #1 Actual output Amps) + (Charger #2 Actual output Amps) =
“System Total BULK output” Amps (for the stacked pair).

This “Total bulk output current” flows into the battery bank. As this total
bulk current is split/distributed within the bank thru each individual parallel
and/or series connected battery, the current each battery “sees” must not
exceed each individual battery’s max allowed charge current as
specified by the battery manufacturer. Since most battery banks are/should
be constructed of the same battery type, model and length of
interconnecting cables, current sharing is roughly equal through each
parallel branch of battery(ies), therefore the above generalizations of “Max
Charge Rate %” can be made for the entire bank.

The Freedom SW’s “Max Charge Rate(%)” setting is set to “100%” by
default, but is adjustable 0-100%, therefore if the charger has max possible
100 A (as in the FSW2012), when set to Max Chg Rate of 100% FSW2012
is capable of delivering its full 100 A into the battery bank. However if this
is too high, the installer/operator may reduce this % setting to suit the
system battery type and bank requirements/limitations, to avoid overheating
the battery bank. The user/installer is responsible for configuring the
charger to ensure the battery manufacturer’s recommended max charge
rate Amps is not exceeded for longest battery life and best performance.

Calculations

Examples

Once installed and configured, each Freedom SW charger calculates its
own actual bulk charge current limit as follows:

(User selectable “Max Charge Rate” %) x (User selectable Battery Bank
Ah capacity) = Actual maximum charger #1 output Amps in bulk mode
(note: Limited to the Charger’s maximum capacity) then,

40 Freedom SW Owner’s Guide

Example 1: In a system composed of two stacked FSW2012’s, industry
commonly accepted practice suggests a typical Flooded battery bank of
capacity (C) 400 Amp-hours should not be charged at a rate in excess of
25% of “C”. i.e. 25% x 400(Ah) = 100 Amps. Therefore, when configuring
the two stacked Freedom SW chargers, each charger must be limited to
contributing max 50 A into the common battery bank. This is accomplished

Freedom SW 3K2K InvChg Owners Guide.book Page 41 Wednesday, October 9, 2013 1:34 PM

by setting each charger’s “Max Charge Rate”% setting to deliver ½ of the
desired total battery bank charge rate of 100 A, i.e. In this example, each
charger “Max Charge Rate” should be set to at most “50%” therefore 50% x
(charger max capacity of 100 A) = 50 Amps actual max output, therefore
since we have two chargers 50 A + 50 A = 100 A which is the max bulk
current this battery bank can accept.

Example 2: The Freedom SW3012 includes a 150 A charger, when using
two stacked Freedom SW3012 inverter/chargers connected to the same bat­tery bank, a total of 300 A of bulk charging is possible.

In a system composed of two stacked FSW3012’s. Industry commonly
accepted practice suggests, a typical Flooded battery bank of capacity (C)
400Amp-hours should not be charged at a rate in excess of 25% of “C” i.e.
25% x 400(Ah) = 100 Amps. Therefore, when configuring the two stacked
Freedom SW chargers, each charger must be limited to contributing max
50 A each into the common battery bank. This is accomplished by setting
each charger’s “Max Charge Rate”% setting to deliver ½ of the desired total
battery bank charge rate of 100 A. i.e. in this example, each charger “Max
Charge Rate” should be set to “33%” x (charger max capacity of 150 A) =
50 A actual max output, therefore 50 A + 50 A = 100 A which is the max
bulk current this battery bank can accept.

Example 3: The Freedom SW 3012 includes a 150 A charger, when using
two stacked Freedom SW3012 inverter/chargers connected to the same bat­tery bank, a total of 300 A of bulk charging is possible.

In the above system composed of two stacked FSW3012’s. Industry
commonly accepted practice suggests, a typical Flooded battery bank of
capacity (C) 1000 Amp-hours should not be charged at a rate in excess of
25% of “C” i.e. 25% x 1000(Ah) = 250 Amps. Therefore, when configuring

Configuring the Freedom SW using the SCP

the two stacked Freedom SW chargers, each charger must be limited to
contributing max 125 A each into the common battery bank. This is
accomplished by setting each charger’s “Max Charge Rate”% setting to
deliver ½ of the desired total battery bank charge rate of 250 A, i.e. in this
example, each charger “Max Charge Rate” should be set to “83%” x
(charger max capacity of 150 A) = 125 A actual max output, therefore
125 A + 125 A = 250 A which is the max bulk current this battery bank can
accept.

Example 4: The Freedom SW 3024 includes a 75 A(@24 V) charger, when
using two stacked Freedom SW3024 inverter/chargers connected to the
same battery bank, a total of 150 A(@24 V) of bulk charging is possible.
Industry commonly accepted practice suggests, a typical Flooded battery
bank of capacity (C) 600 Amp-hours (@ 24 V) should not be charged at a
rate in excess of 25% of “C” i.e. 25% x600(Ah) = 150 Amps (@24 V).
Therefore, when configuring the two stacked Freedom SW chargers, each
charger must be limited to contributing max 75 A (@24 V) into the com­mon battery bank. This is accomplished by setting each charger’s “Max
Charge Rate”% setting to deliver ½ of the desired total battery bank charge
rate of 150 A
be set to “100%” x (75 A charger max capacity) = 75 A actual max output,
therefore 75 A + 75 A = 150 A which is the max bulk current this battery
bank can accept.

Configuring the Freedom SW using the SCP

the Xanbus SCP displays the basic settings by default. To view the
advanced settings, you must perform a special keypress (see “Selecting
Advanced Settings From the Device Setup Screen” on page 43).

NOTE:

This keypress enables the advanced settings for every device in the
system. After performing the keypress, Advanced Settings appears in
the list and Basic Settings disappears.

FIRE AND ELECTRICAL SHOCK HAZARD

The advanced settings are intended for qualified installation/service
personnel only. Before changing advanced settings, you must be familiar
with the settings and the system-wide impact of changing those settings.
Setting parameters incorrectly could damage connected equipment (such
as batteries) or could severely affect the performance of your system.
Incorrect charging configuration can lead to battery damage and risk of
fire.

The Freedom SW advanced settings include menus for configuring:

• Inverter settings (see page 46).

• Charger settings (see page 48).

• AC transfer limit settings (see page 52).

• Generator support settings (see page 53).

• Stacking operation, including customizing the default model name of
the Freedom SW, and setting its network device number. Setting the
device number is important when multiple Freedom SWs are on the
Xanbus network and sharing connections such as AC loads, utility
grid, and generator. The device number is also used when configuring
paralleled Freedom SWs for Master-Slave operation (see page 54).

• Restoring default settings (see page 57) and other advanced features
(see page 57).

Freedom SW advanced menu screen lists status information and settings
which require that you understand and plan for the changes you make. You
may not have to adjust these settings as part of regular operation.

The SCP shows the Freedom SW basic menu by default. To view the
advanced settings menu, you have to activate it by following the procedure
below.

To select the Advanced Settings menu screen:

1. On the FSW3012 00:Setup screen (Figure 21), press the Enter, Up
arrow, Down arrow buttons simultaneously to make Advanced
Settings appear in the list.

2. On the FSW3012 00:Setup screen, press the down arrow button until

Inverter Settings Description

Item Description

Search Delay Search Delay sets the time between search pulses. When searching for

loads, the Freedom SW sends out search pulses to determine if a load
is present. If the Freedom SW finds a load above the Search Watts
setting, the inverter turns on. Freedom SW power draw while in search
mode decreases when Search Delay is increased, but the Freedom
SW’s response time to active loads is slower.

Configuring the Freedom SW using the SCP

LBCO Delay Settings

The Low Batt Cut Out setting is the lowest battery voltage level
acceptable for use by the inverter. When the batteries discharge to the Low

Batt Cut Out setting, and are held at or below this level for the LBCO
Delay time, the inverter output shuts down and transfers any available AC

source (generator or grid) to the charger to bring the battery level back
above the Low Batt Cut Out setting. After shutdown, the inverter does
not support any AC loads, and AC loads must be powered by either a
generator or utility power.

• If using an automatic generator starting system, it is recommended to
set the Xanbus AGS voltage trigger setting higher than the Freedom
SW Low Batt Cut Out voltage.

• Although not recommended, if using an automatic generator starting
system with the start trigger set to the same voltage as the LBCO
voltage, do not set the LBCO Delay to less than the amount of time it
takes the generator to start and connect.

Otherwise – in both of the scenarios above – inverter output turns off before
the generator automatically starts, causing the battery voltage to recover
slightly. This may then stop the Xanbus AGS from starting the generator or
result in the Freedom SW cycling on and off multiple times before the
generator automatically starts.

Battery Charger Functions

When AC power is available, the Freedom SW can operate as a battery
charger. Different battery types and chemistries require different charging
voltage levels. Not charging batteries at the required levels can shorten
battery life or damage the batteries. The Freedom SW is configured at the
factory to work with the battery types recommended for inverter
applications. If the default settings do not work for your specific
installation, you can adjust the charge stage settings (as recommended by
the battery manufacturer) on the Custom (Battery) Settings menu (see
page 50).

NOTE: This information is provided for guidance only. Variations in
battery chemistry and site-specific environmental considerations mean
that you should consult your system designer or battery manufacturer for
specific recommendations for appropriate battery voltage and current

upstream distribution panel. The Freedom SW limits the maximum input
current to this setting by derating its charging current to an equivalent of
80% of the AC breaker size. If the connected loads exceed the AC1
breaker setting, the AC breaker trips. The breaker may not trip if grid
support is enabled and battery voltage is above the Grid Supp Volts
setting, or if peak load shave is enabled and the load shave time window is
active.

NOTE: It is recommended to leave this setting to its default value and not
to set it to the maximum allowed. Doing so might inadvertently derate

Gen Support

Configuring the Freedom SW using the SCP

GEN Support allows power to be automatically drawn from the batteries to
assist an AC generator to support heavy loads (i.e., loads that exceed the
available current from the generator).

Generators have a limited output current and it is possible to reach this limit
when operating heavy loads. The Freedom SW is designed to assist the
generator when heavy current demands load down the generator by
supplying additional power from the batteries.

In addition, the battery charger can reduce its charging current to the
batteries so the combined charge AC current and total load current does not
exceed the capacity of the generator or trip its output breakers or fuses.

Configuring the Freedom SW using the SCP

Setting the Device Number

Setting the device number gives a Xanbus-enabled device a unique identity
when several devices of the same type are installed in the power system
network. When each identical device has a unique number, the Xanbus SCP
can correctly identify and display status information for each device.
A device number consists of two digits ranging from 00 (default) to 31.

If only one of each type of device is installed in the network, you do not
need to set the device number. However, setting the device number to a
value other than 00 is recommended in case you need to use the
Restore Defaults command (which resets the device number to 00).
After performing the command, checking that the device number has
returned to 00 indicates that the command was successfully completed.

To set the Freedom SW device number:

1. On the Freedom SW Setup menu, select Advanced Settings.

If Basic Settings appears instead of Advanced Settings on the
Setup menu, display Advanced Settings by pressing
Enter + Up arrow + Down arrow simultaneously.

On the Advanced Settings menu, select Stacking and press Enter.

2. On the Stacking menu, select Dev Number.

3. Press Enter to highlight the instance number.

4. Use the up and down arrow buttons to adjust the two-digit identifier
number.

5. Press Enter.

Battery Charging Reference

This section describes the multistage charging algorithm (formula) of the
Freedom SW.

Battery Types

Freedom SW charges flooded (or wet) lead-acid, Gel, AGM (absorbed
glass mat), and custom batteries.

• Flooded (or wet) batteries have removable battery caps for refilling
with distilled water and testing the electrolyte.

• Gel batteries have the electrolyte in the form of a gel rather than a
liquid and do not require topping up. Gel batteries are sealed and the
battery caps are not removable.

• AGM (Absorbed Glass Mat) batteries are similar to gel batteries
except that the electrolyte is absorbed into a fiberglass matting.

• Custom battery is configured by the dealer, factory, or service center
for battery types other than those listed above.

RISK OF BATTERY DAMAGE

Since the Freedom SW can only select one battery type setting for all
batteries connected to its bank, do not mix battery types. All connected
batteries should either be: Flooded (or wet) or Gel or AGM or Custom.

Charge Algorithm Stages

Three-Stage charging

If three-stage charging is enabled, the Freedom SW will charge batteries in
a sequence known as three-stage charging. Whenever qualified AC power
is present at the inverter’s input, it passes power through to the connected
load and begins charging the batteries. The charging voltage delivered to
the battery depends on the battery’s:

• type setting

• temperature (by switch setting or battery temperature sensor)

• state of charge

The three automatic stages are:

• bulk

• absorption

•float

See Figure 32 for a graph of the three-stage charging profile.

There is a fourth stage, equalization, which is initialized manually as it is
only performed occasionally and only on flooded (or wet) batteries.

The charging cycle is a multi-stage (three-stage) process. Whenever
qualified AC power is present at the inverter’s input, it passes power
through to the connected load and begins charging the batteries.

Battery Charging Reference

NOTE:

When the charge cycle is interrupted, the charger will restart charging at
the beginning of the multi-stage algorithm.
Exit Current Threshold can be effectively disabled by programming the
amp-hour capacity to the minimum. In this case, absorption will only exit
once the Max Absorption timer expires.
Charge current during equalize state (optional state not shown here) is
normally limited to 10% of the programmed amp-hour capacity setting. If
this setting is programmed to the maximum, the charge current during
equalize is instead limited to whatever is programmed for the maximum
current limit of the unit.
Synchronized charge states are active when more than one charging
device is connected in the system via the Xanbus network.

• The first unit (Freedom SW) to enter bulk, causes all other chargers to
enter bulk.

• The first Freedom SW to enter absorption causes all other Freedom
SWs to enter absorption.

• The last Freedom SW ready to exit absorption triggers all Freedom
SWs to exit absorption and exit charge.

Figure 32

97-0019-01-01 59

Three-Stage Battery Charging Cycle

Bulk charge is the first stage in the charging process and provides the
batteries with a controlled, constant current. Once the battery voltage rises
to the absorption voltage threshold, the charger switches to the absorption
stage.

Bulk Stage

Freedom SW 3K2K InvChg Owners Guide.book Page 60 Wednesday, October 9, 2013 1:34 PM

Battery Charging Reference

Absorption Stage

During the absorption stage, the Freedom SW begins operating in constant
voltage mode and the current falls gradually as the amp hours are returned
to the battery. By default, the bulk and absorption voltage settings are the
same for all battery types. The voltage limit settings for bulk and absorption
can be adjusted independently if the battery type is set to Custom.

Once the Freedom SW reaches the Bulk (Absorption, after the first 60
minutes) Voltage setting, the Freedom SW will operate in constant voltage
mode, providing only the necessary current to maintain the voltage setting.
As the amp hours are returned to the battery, the current required to
maintain the voltage setting falls gradually.

The Freedom SW transitions to the float stage if either one of the following
two conditions are met:

1. The charge current allowed by the batteries falls below the exit current
threshold, which is equal to 2% of the programmed battery capacity
(for a 500 amp-hour battery bank, this would be 10 amps), for three
minutes.

2. The Freedom SW has been in absorption for the programmed
maximum absorption time limit. The default is 3 hours, but the time
limit is programmable from 1 minute to 8 hours.

NOTE: If there are DC loads on the batteries, the charger’s current may
never decrease to a level to initiate the next stage of charging. In this case,
the charger would stay in absorption until the Absorb Time setting is
reached.

NOTE: To make sure the charger does not remain in absorption for too
long, adjust Absorb Time on the Charger Settings menu. The timer
begins at the start of the absorption stage and terminates absorption
charging if the charge current does not decrease to below 2 per cent of the
battery capacity before the Absorb Time setting expires. The Absorb

Time setting may be increased if the charge cycle continually runs the full
Absorb Time in the absence of DC loads. This is an indication of too
large a battery bank for the selected Absorb Time setting.

Float Stage

Float charge maintains the batteries slightly above the self discharge
voltage of the batteries. The charge current in float is the current necessary
to maintain the batteries at the Float Voltage setting, limited only by the
inverter's capability or other settings that limit the inverter's maximum
charge rate. Float charging reduces battery gassing, minimizes watering
requirements (for flooded batteries), and makes sure the batteries are in a
constant state of readiness. When three-stage charging is selected, the
charger automatically switches to the float stage after the batteries have
received a bulk and absorption charge (see Figure 32). The batteries are
maintained at the default float voltage level for the selected battery type or
the voltage selected under Float Voltage on the Custom Battery
Settings menu.

NOTE: The battery voltage can increase above the float voltage when
using an external charging device such as PV arrays, wind turbines, and
micro-hydro generators. Be sure to include appropriate charge
management equipment with all external DC sources.

Two-Stage Charging Process

Two-stage (or no float) mode differs from an ordinary three-stage charge
mode in that it does not continuously maintain the battery at float voltage.
Instead, the Freedom SW begins charging the battery in bulk mode
whenever the battery voltage drops below the recharge level. While the
battery voltage is above the recharge level the inverter’s AC transfer switch
continues to pass power through from the utility grid to the loads, but does
not actively charge the batteries.

Two-stage mode increases efficiency of utility connected systems by
reducing the amount of power consumed by the inverter and batteries
compared to when the battery is continuously maintained at Float
Voltage. This feature can extend the life of most batteries.

If the AC input fails or drops below the lower VAC limit (as set in

range. If the batteries are already nearly full, the charge cycle will take little
time to complete.

Equalize Charging

Many battery manufacturers recommend periodic equalize charging to
counter cell charge imbalance and capacity-robbing electrolyte
stratification. Equalizing helps to improve battery performance and lifespan
by encouraging more of the battery material to become active.

Battery equalization is a controlled overcharging method that mixes up
stratified electrolyte and reactivates unused areas of the plate material.
Periodic equalizing can help to regularly restore batteries to a full and
healthy state of charge.

Consult the battery manufacturer's recommendation for equalize charging
settings. Sealed batteries should never be equalized. Consult the battery
manufacturer for optimal charging procedures when using sealed batteries.

When Equalize mode is enabled, the battery is charged from bulk to
absorption, and then to the equalize phase. The Freedom SW will transition
from the absorption phase to equalize if:

• the DC charge current is below 2% of the configured battery capacity
(for example, 8.8A for 440Ah).

• the absorption time is exceeded (for example, 180 min).

After absorption, the maximum charge DC current is set to 10% of battery
capacity (for example, 44A for 440Ah). See Figure 34. This constant current
charge will continue until the voltage has increased to the equalize voltage at
which point the battery will be regulated at the temperature-compensated
equalize voltage.

Battery Charging Reference

If the battery capacity is set to zero (Ah=0 effectively disables the exit
current criteria for the absorption charge stage making the absorption stage
defined by time only), the equalize charge current is fixed at maximum
100% of the charge rate.

Equalization duration is fixed at one hour.

Troubleshooting

General Troubleshooting Guidelines

This section will help you narrow down the source of any problem you may
encounter. Please read the following troubleshooting steps:

1. Check for a warning or fault message on the Xanbus SCP or a fault
code on the inverter information panel. If a message is displayed,
record it immediately.

2. As soon as possible, record the conditions at the time the problem
occurred. These details should include the following information:

• loads the Freedom SW was running or attempting to run

• battery condition at the time of failure (battery voltage or

temperature, for example), if known

• recent sequence of events (for example, charging had just

finished, utility grid had failed but the inverter did not come on)

• any known unusual AC input factors such as low voltage or

unstable generator output

• extreme conditions which may have existed at the time

(temperature or moisture, for example).

3. Attempt the solution indicated in these guidelines.

4. If your inverter information panel or Xanbus SCP is not displaying a
Fault light, check the following list to make sure that the present state
of the installation allows proper operation of the unit. Read these
guidelines carefully.

❐ Is the Freedom SW located in a clean, dry, adequately ventilated area?

❐ Have the AC input breakers opened? If so, your pass-through load may

have exceeded the rating of one or more of the input breakers.

❐ Are the battery cables adequately sized and short enough? See the

Installation Guide for more information.

❐ Is the battery in good condition and are all DC connections tight?

❐ Are the AC input and output connections and wiring in good

condition?

❐ Are the configuration settings correct for your particular installation?

❐ Are the display panel and the communications cable properly

connected and undamaged?

❐ Is the battery temperature sensor and its cable properly connected and

undamaged?

5. Contact Customer Service for further assistance. Please be prepared to
describe details of your system installation and provide the model and
serial number of the unit. See the front and/or back of the manual for
contact information.

Troubleshooting

Inverter Applications

The Freedom SW performs differently depending on the AC loads
connected to it. If you are having problems with any of your loads, read this
section.

Resistive Loads

Resistive loads are the easiest and most efficient to drive. Voltage and
current are in phase, which means they are in step with one another.
Resistive loads generate heat in order to accomplish their tasks. Toasters,
coffee pots, and incandescent lights are typical resistive loads. It is usually
impractical to run larger resistive loads—such as electric stoves and water
heaters—from an inverter due to their high current requirements. Even
though the inverter may be able to accommodate the load, the size of
battery bank will limit inverter run time.

Motor Loads

Induction motors (AC motors without brushes) require up to six times their
running current on startup. The most demanding are those that start under
load (for example, compressors and pumps). Of the capacitor start motors
(typical in drill presses and band saws, for example), the largest you can
expect to run is 1 horsepower. Universal motors are generally easier to start.
Check that the Locked Rotor Amps (LRA) rating of the motor load does not
exceed the maximum surge current rating of the inverter. Since motor
characteristics vary, only testing will determine whether a specific load can
be started and how long it can be run.

If a motor fails to start within a few seconds or loses power after running for
a time, it should be turned off. When the inverter attempts to start a load that
is greater than it can handle, the inverter may shut down from an AC
overload fault.

Problem Loads

Very Small Loads If the power consumed by a device is less than the
threshold of the search mode circuitry, and search mode is enabled, the
inverter will not run. Most likely the solution will be to disable Search
mode or lower the sense threshold.

Fluorescent Lights and Power Supplies Some devices cannot be
detected when scanned by search mode circuitry. Small fluorescent lights
are the most common example. Some computers and sophisticated
electronics have power supplies that do not present a load until line voltage
is available. When this occurs, each unit waits for the other to begin. To
drive these loads, either a small companion load like a light bulb rated for
more than the Search Watts setting must be used to bring the inverter out
of search mode, or the inverter may be programmed to remain on by
disabling Search mode. (See “Using Search Mode” on page 34.)

Clocks You may notice that your clocks are not accurate. Some of the
clocks on your appliances may reset when the Freedom SW is in
search mode.

Searching When the inverter is in search mode, it may fail to start some
loads even though the rated wattage on the load is more than the Search
Watts setting. Disable Search or apply an additional load (companion
load) to make the inverter exit search mode.

Fault Types

There are three types of fault messages: automatic faults, manual faults, and
escalating automatic faults. Table 3 describes how they differ in their
behavior and how you can respond to them when they appear on the SCP.

Troubleshooting

menu or on the menu for the Xanbus-enabled
device that generated the fault (if the fault
condition still exists, the fault message reappears)

• correcting the condition that caused the fault.

Escalating
automatic faults

Clear automatically if the fault condition goes away,
just like an automatic fault.
However, if an escalating automatic fault occurs
several times within a defined time period, the
escalating automatic fault becomes a manual fault,
requiring user intervention. For example, if an AC
Overload fault occurs three times in five minutes, it
will no longer clear itself and become a manual fault.
Then you must identify the problem, correct the fault
condition, and clear the fault.

Troubleshooting

Troubleshooting the Freedom SW via the SCP

The Freedom SW is designed with a number of protection features to
provide efficient operation. If, however, you have any problems operating
your inverter/charger read this troubleshooting chapter.

If you cannot resolve the problem, record the information about your
system. This information will help your dealer or customer service to assist
you better when you contact them.

ELECTRICAL SHOCK HAZARD

Do not disassemble the inverter/charger. The Freedom SW contains no
user-serviceable parts.

When a fault or warning message appears, you can acknowledge the
message to clear the screen. To acknowledge a fault or warning message,
press the Enter button on the SCP. This action does not clear the fault or
warning condition, so you should consult Table 4 for suggested actions after
you have acknowledged the message. Refer to the Xanbus System Control
Panel Owner’s Guide for more information on faults and warnings.

Fault Types

There are three types of fault messages: automatic faults, manual faults, and
